Does anyone know the p/n for the caliper bolt for the LS1 front brakes? Not the banjo bolt...the bolt that mounts the calipers to the spindle.

Do you mean the bolt that mounts the abutment bracket to the spindle?

Might be 18023646, I can't tell for sure. These are, I think, the larger bolts that do not go into the guide pins, they hold the cage like bracket to the steering knuckle and do not go into the caliper itself.

Best to check with a partsman, if they have them in stock easy to compare. The guide pin bolts are 8mm.

Guidepin bolts are the ones that slide into the caliper. They don't bolt the caliper to the spindle. It must be the other ones you have listed, but I don't know for sure if that's the right part #.

Yeah..it's the first one I need. Not the guide pins, but the ones that mount the caliper brackets (cage) onto the spindles. Meaing, if you were to remove the entire caliper assembly fromt he spindle...these are the 2 that need to be taken out. Thanks for the p/n, and I'll confirm with a dealership before ordering them.

Sounds good. That cage is called the abutment bracket.
